IMPROVEMENT lN C'OOKlNG-STOVES.

Specification forming part of Letters Patent No. 159,788, dated February16,1875; application filed January 30, 1875.

To all whom it may concern:

Be it known that I, EDWIN O. BRINCKER- HOFF, of the city, county, andState of New York, have invented a new and useful Improvement inCooking-Stoves, of which the following is a specification:

Figure 1 is a top view of my improved stove, part of the top plate beingbroken away. Fig. 2 is a horizontal section of the same taken throughthe line o 0, Figs. 4 and 5. Fig. 3 is a horizontal section of the sametaken through the line w 20, Figs. 4 and 5. Fig. 4 is a verticalcross-section of the same taken through the line 00 00, Figs. 1, 2, and3. Fig. 5 is a vertical cross-section of the same taken through the linew m, Fig. 1. Fig. 6 is a vertical longitudinal section of the same takenthrough the line 3 3 Fig. 1. Fig. 7 is a vertical longitudinal sectionof the same taken through the line y y, Figs. 1, 2, 3, and 4. Fig. 8 isa vertical crossseotion of the same taken through the line 2 2, Figs. 1,2, 3, and 4.

Similar letters of reference indicate corre sponding parts.

My invention has for its object to furnish an improved cooking-stove,the flues of which shall be so arranged that when the stove is used forbaking purposes it may be heated quickly,thoroughly, and uniformly, andwith a comparatively small amount of fuel, and that when used forboiling purposes the entire stove need not be heated.

The invention consists in the combination of the side and bottom flues,the side fluespace, the front flue-space, the inner side fluespace, theinner rear flue-space, and the outer rear flue-space with each other,the outer and inner cases of the stove, and the chimney-flue, in thecombination of the outer side flues with the vertical side flues, theouter rear flue-space, and the chimney-flue, and in the combination ofthe sliding damper with the set of flues used when baking, the set offlues used when boiling, and the chimney-flue, as hereinafter fullydescribed.

A is the outer case of the stove, and B is the inner or oven case. 0 isthe fire-box, which is placed in the middle part of one side of thestove, as shown in Figs. 1, 2, and 4. D are the oven-doors, which areplaced in the front of the stove. E is the exit or chimney flue, whichis placed at the middle part of the rear of the stove. At the side ofthe stove opposite the firebox are formed three flue spaces, by theinterposition of two vertical plates between the side plates of theouter and inner cases. At the rear side of the stove are formed twoflue-spaces, by the interposition of a vertical plate between the rearplates of the outer and inner cases.

I will describe the various flues of the stove in connection with thecourse of the products of combustion in passing through them, firstdescribing the flues brought into use when the stove is to be heated forbaking purposes, and then describing the flues brought into use when thestove is to be used for boiling purposes.

The products of combustion from the firebox 0 pass up into the spacebctweenthe top plates of the two cases A B, pass across the stovelaterally, and descend through the holes 1F 2F 3F 4F 5F into the middleflue-space at that side of the stove, as indicated by the arrows 1. Theholes F are made of such a size that the sum of their areas may be equalto the area of the chimney-flue, and generally the sum of the areas ofthe flues through which the products of combustion may be passing at thesame time, and in the same direction, is equal to the area of thechimney-flue. The products of combustion thatpass down through the hole1F pass down through the vertical flue 1F pass through the bottom flue1F return through the bottom flue 1F pass up through the vertical flue1F, pass down through the vertical flue 1F pass through the bottom flue1F and through the elbow-flue 1F into the flue-space G at the fire-boxside of the stove. The products of combustion-that pass down through thehole 2F pass down through the vertical flue 2F pass through the bottomflue 2E return through the bottom flue 2F pass up through the verticalflue 2F pass down through the vertical flue 2F through the bottom flue21F, and through the elbowflue 2F into the side flue-space G. Theproducts of combustion that pass down through the hole 3F, pass downthrough the vertical flue 3F pass through the bottom flue 3F, andthrough the elbow-flue 3F into the side fluespace G. The products ofcombustion that pass down through the hole 4F pass down through thevertical flue 4F pass through the bottom flue 4E return through thebottom flue 41?, pass up through the vertical flue 4F, pass down throughthe vertical flue 4E pass through the bottom flue 4F", and through theelbowflue 41* into the side flue-space G. The products of combustionthat pass down through the hole 5F pass down through the vertical flue51?, pass through the bottom flue 51, return through the bottom flue 5Fpass up through the vertical flue 5F, pass down through the verticalflue 5E pass through the bottom flue 5F, and through the elbowflue 5!?into the side flue-space G. The course of the products of combustionthrough the vertical and bottom flues F is indicated by the arrows 2 and3. The products of combustion pass through the flue-space Gr, around thefirebox-door frame, and escape through an opening at the lower forwardend of said flue-space G into the front flue-space H, as indicated bythe arrows 4. The products of combustion pass through the frontflue-space H, around the oven-door frame, and escape at the opposite endof said front flue-space H, into the inner side flue-space I, asindicated by the arrows 5. The products of combustion pass back throughthe flue-space I, as indicated by the arrows 6, and pass at the rear endof said flue-space I into the inner rear flue-space J. The products ofcombustion pass across the stove through the inner rear flue-space J, asindicated by the arrows 7, and escape through an opening at the otherend of said flue-space J into the outer rear flue-space K, and passthence through an opening, 6 in the middle part of the rear plate of theouter case A, into the chimney or exit-flue E, as indicated by thearrows 8. The outer rear flue-space K is divided into two equal parts bya vertical partition, k, as shown in Figs. 2 and 3, and upon the otherside of the said partition k a second opening, 6 leads into the chimneyor exit-flue E. L is a damper, operated by a handle passing out throughthe rear plate of the outer case A to close either of the openings 6 0When the stove is to be used for baking purposes, the damper L isadjusted to open the openings 6 and close the openings 6 which causesthe products of combustion to take the course hereinbefore described,heating the whole SCOVG evenly and uniformly.

When the stove is to be used for boiling purposes, the damper L isadjusted to close the opening 6 and open the opening 6 With thisadjustment of the damper L the products of combustion that pass downthrough the vertical flue lF of the middle side flue-space, pass intothe flue 1M, and thence into the outer rear flue-space K. Theproducts ofcombustion that pass down through the vertical flue 2F pass out into theflue 2M, down into the flue 2M up through the flue 2M and through theflue 2M into the outer rear flue-space K. The pro ducts of combustionthat pass down through the vertical flue 3E, pass out into and upthroughthe vertical flue3M,and thence through the flue 3M into the outerrear flue-space K. The products of combustion that pass down through thevertical flue 413 pass out into and up through the vertical flue 4M,down through the flue 4M up through the flue 4M and through the flue 4Minto the outer rear fluespace K. The products of combustion that passdown through the vertical flue 5F pass out into and up through thevertical flue 5M, down through the flue 5M up through the flue 5M andthrough the flue 5M into the outer rear flue-space K. The course of theproducts of combustion through the flues M is indicated by the arrows 9.The products of combustion pass through the outer rear flucspace K, andthrough the opening 0 into the chimney or exit-flue E, as indicated bythe arrows 10.

The draft of the stove is regulated by the damper N, placed in thechimney-flue E above the top of the stove.

Having thus described my invention, I claim as new and desire to secureby Letters Patcut- 1. The combination of the side and bottom flues F,the side flue-space G, the front fluespace H, the inner side flue-spaceI, the inner rear fluespace J, and the outer rear flue-space K with eachother, with the outer and inner cases, A B, and the chimney-flue E, insubstantially the manner herein shown and described.

2. The combination of the outer side flues M with the vertical sideflues F, the outer rear flue-space K, and the chimney-flue E, insubstantially the manner herein shown and described.

3. The combination of the sliding damper L with the set of flues F G H IJ K, the set of flues F M K, and the chimney-flue E, substantially asherein shown and described.
